UNITED STATES PATENT, OFFICE.

EDWARD E. KYLE, OF NEWVVILLE, ASSIGNOR OF THREE-FOURTHS TO MIL- TON H. \VAGONER, GEO. XV. NORTH, AND THEODORE OORNMAN, ALL OF CUMBERLAND COUNTY, PENNSYLVANIA.

NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 349,724, dated September 28, 1886.

Application filed April 8, 1986 To all whom it may concern.-

Be it known that I, EDWARD E. KYLE, a citizen of the United States, residing at Newville, in the county of Cumberland and State of Pennsylvania, have invented certain new and useful Improvements in Nut-Locks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it ap-. IO pertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification. y W

The invention will first be describedin connection with the drawings, and then pointed out in the claim.

Figure 1 of the drawings is a plan View showing the burr locked and the nut in its socket. Fig. 2is alongitudinalseetion on line was of Fig. 1. Fig. 3 is a bottom view of the washer.

In the drawings, A represents the beam or plate or timber through which passes the bolt 2 5 B, whose neck is not round, to prevent it from turning. v

a a are indentations, into which fit the teats c c of the washer G. This washer has the central hole, 0', for the screw-bolt B, and the groove 0 below which is the slot 0 1 In this slot moves the pin (1 on the under side of the slide D, which works in the provided with a top stud, d,

groove 0 and is Serial No. 198,210. (No model.)

E is a detent pivoted at e, and having the notch e, in which fits the edge of the stud d.

F is a spurred burr having the socketf, in which fits the nut G, a sufficient part of said nut'being left to project so as to allow it to be easily grasped by the Wrench in order to turn it 011 or off the screw. The burr and nut will turn together on the screw until firmly in place. Then the slide D is moved up until the Stud (1' enters one of the notches f in the burr. It then becomes impossible for the nut to turn on the bolt.

To prevent the slide from being carried back by jars, I turn down the detent E so as to brace the stud d against any rearward movement.

What I claim as new, and desire to protect by Letters Patent, is-

The combination, with a bolt and nut, of the washer 0, having teats-c c, the central hole, 0,

the groove 0 and the slot 0 the slide D, having pin d and top stud, d, the pivoted detent E, notched at e, and the burr F, having socket f, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
